Châteauneuf (Kibbutz Margaliot or Castellum Hunin) is a Crusader castle that helped Hugh of St. Omer to control the Upper Galilee region that dominated the vital route from Damascus to Tyre. It was built around 1107 in The Kingdom of Jerusalem.

After changing hands several times, Châteauneuf was transferred to the Knights Hospitallers but they never took hold of the castle. The castle changed hands again between the Muslims and Crusaders several times when King Guy de Lusignan turned it over to Joscelinthe III of Courtenay in 1186. In 1187 after a siege of 5 months, the fortress surrendered to Saladin. The Castle was destroyed in 1226 by the Muslims and surrendered once more in 1240 to the Crusaders. In 1266 the fortress was conquered by the Mamluk warlord Baibars, who restored it in 1267. Part of the building collapsed in the earthquake of 1837. Today the remains of the castle’s large halls can still be seen, including water cisterns and a moat. The top of the castle, situated on the Naphtali mountain range, provides a magnificent view of the Hula Valley, all the way to Nimrod Fortress and Mt. Hermon on the Golan Heights.
